SEALING MEANS.

Application filed June 13, 1921. Serial No. 477,006.

T all whom/it may concern: a

Be it known thatI, VVINFRED M. BnooKs, a citizen of the UnitedzStates, and a resident of SouthOrange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sealing Means,-'of which the following is a and flexibility of the wire element associ-" ated with the sealing medium without un duly increasing the diameterof the wire element. 7

In the accompanying drawing the inventlon is disclosed in a concrete and preferred form inwhich Figure'l is a general View in plan of a sea-1 embodying theinvention: i

Figure 2 is a detail View of a portion of the wire element used: and

Figure?) is a cross-sectional View onithe line 3 3 of Figure 2..

1 indicates the sealing medium, which may be a piece of lead or other soft and compressible material, and2 indicates the wire element, one end 3 of which is embedded in the sealing element and the other end 4 of which'passes through a slot in the sealing'element in a manner well understood, the wire being bent back upon itself, as shown, to. form a loop.

I have found that, by making the wire element in the form of a strand composed of a plurality of Very fine wires 5, the strength of the wire element may be materially increased without materially increasing its diameter.

It appeared, however, that'the twisted WVlIe strand was not nearly so flexible and pliable as a wire element made of a single wire, but I then found that by crimping the twisted strand in the manner indicated in Figure 2 that additional and requisite plia bility would be afforded without lessening of the strength of the wire element.

I claim:

A wire seal comprising: a soft metal sealing element, and a criinped wire strand associated with said sealing element by being bent back uponitself, said strand consisting of a plurality of wires twisted together.
